WebIn this article an arbitrary Lagrangian–Eulerian (ALE) formulation for modelling cavitation in elastohydrodynamic lubrication (EHL) is derived and applied to line contact geometry. The method is developed in order to locate the position of cavitation onset along the length of the contacting region which gives the transition from liquid to vapour in the fluid. Webin Lagrangian coordinates and invariance the constructed schemes in particular are discussed. Section 6 is devoted to the numerical implementation of the schemes. The results are summa-rized in Conclusion. 2. The one-dimensional SMHD equations in Lagrangian coordinates The SMHD model proposed in [1] in Eulerian coordinates has …
